I think you misunderstand my concern. Going from a system where everyone needs to generate $20k of economic value "to eat" (yes, oversimplification of benefits, but bear with me) to one in which no one needs to generate economic value may have some macro scale inflation issues. Those are the issues a study of UBI needs to cover.
